Body Ratios: "Twice round
the thumb is once round the wrist," said the Lilliputians in Gulliver's
Travels. Students here investigate whether or not the Lilliputians, who
used this ratio to make a shirt for the giant Gulliver, were right. The
lesson demonstrates the integrated approach to mathematics that the MATH
Thematics Curriculum takes, with students using and gaining knowledge
and skills in number sense, ratios, fractions, measurement, making predications,
analysis, and geometric concepts. After exploring and interpreting several
different body ratios, students determine how tall Gulliver would be if
a Lilliputian's average height were that of a sixth grader. The lesson
extends to the outdoors, where students make a lifesize outline of a
shirt for Gulliver.
